I will present the scientific goals and the instrumentation of the SVOM (Space-based Variable astronomical Objects Monitor) mission, which is being developed in collaboration by the French Space Agency (CNES) and the Chinese National Space Administration (CNSA). The SVOM mission, to be launched by the end of 2023, and dedicacted mainly to Gamma-Ray Bursts and other fast transient sources, will carry on board two wide field-of-view instruments: ECLAIRs, a coded mask imaging telesocpe operating in the 4-250 keV energy range, and GRM, a non-imaging gamma-ray spectrometer, operating in the 20 keV-5 MeV energy range. Part of the SVOM payload will also be two narrow field instruments: the MXT, a focussing X-ray telescope sensitive in the 0.2-10 keV energy range, and the VT, an optical telescope. 

The SVOM platform will be able to operate autonomously in space, implying the ability to repoint its narrow field instruments to the coordinates derived for transient sources detected in real time by ECLAIRs. The positions derived on-board will be sent in a few tens of seconds to all ground based observatories for follow-up observations. All instruments are completed and will be integrated soon on the SVOM spacecraft; I will present their expected performance as well as the SVOM observation strategy and data policy.
